Empiricism is a very good thing, and produces excellent results where there is great wealth of natural resources, and unhampered opportunities without the pressure of time in active competition. Could we each of us live through many lives and generations for a thousand years with our eyes and ears open, we might gain experience and wisdom more effectively than is conveyed to us by much teaching and much reading. But when the natural resources dwindle, and the pressure of time grows, when we are pressed out of the favourable position of easy monopoly into one of severe competition, empiricism will not suffice to secure the retention of our advantage. Then practice must be strengthened, advanced, and hastened in its advance, by well matured and applied theory.
